@jsxtools/rollup-plugin-copy

@jsxtools/rollup-plugin-copy is a rollup plugin for copying files during the build process.

Installation

npm install @jsxtools/rollup-plugin-copy

Usage

import { rollupPluginCopy } from '@jsxtools/rollup-plugin-copy';

export default {
  input: 'src/index.js',
  output: {
    file: 'dist/bundle.js',
    format: 'es'
  },
  plugins: [
    rollupPluginCopy({
      rootDir: 'src',
      distDir: 'dist',
      include: ['src/**/*.css', 'src/**/*.png', 'src/**/*.svg'],
      exclude: ['src/**/*.test.*']
    })
  ]
};

Features

• Copies files from source to destination with glob pattern support.
• Only copies files that have changed using modification time and SHA-256 hash comparison.
• Maintains a cache to avoid unnecessary file operations.
• Handles file additions, changes, and deletions during development.
• Uses Copy-on-Write (CoW) optimization when available (APFS, Btrfs, XFS).
• Integrates with Rollup's asset system.

Configuration Options

• cacheFile - Cache file for tracking changes (default: cpconfig.cpbuildinfo).
• include - Glob patterns for files to include (string or array).
• exclude - Glob patterns for files to exclude (string or array).
• distDir - Destination directory to copy files to (default: dist).
• workDir - Current working directory (default: current process directory).
• rootDir - Source directory to copy files from (default: src)

Examples

Copy CSS and Image Files

rollupPluginCopy({
  rootDir: 'src',
  distDir: 'dist',
  include: [
    'src/**/*.css',
    'src/**/*.png',
    'src/**/*.jpg',
    'src/**/*.svg'
  ]
})

Copy with Exclusions

rollupPluginCopy({
  rootDir: 'assets',
  distDir: 'public',
  include: ['assets/**/*'],
  exclude: [
    'assets/**/*.test.*',
    'assets/**/.*'
  ]
})

Caching

The plugin maintains a cache file (default: cpconfig.cpbuildinfo) that tracks file modification times and SHA-256 hashes. This enables:

• Only changed files are copied (based on mtime comparison)
• Content verification using SHA-256 hashes when mtime differs
• Detection of removed files for cleanup
• Minimal file system operations during development
• Incremental builds with accurate change detection

API

The plugin exports both the main plugin and a separate API:

• rollupPluginCopy() - The main Rollup plugin
• CopyAPI - Available via @jsxtools/rollup-plugin-copy/api

import { CopyAPI } from '@jsxtools/rollup-plugin-copy/api';

const copyApi = new CopyAPI();
copyApi.init({
  rootDir: 'src',
  distDir: 'dist',
  include: ['src/**/*.css']
});
